🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Lost Keys
1) Contact a locksmith who specializes in automotive keys or your dealership 2) Provide proof of ownership (registration, title, ID) 3) They'll either cut new keys by code or reprogram your car's system 4) This is expensive ($200-$800) as the immobilizer may need resetting.
Key Fob Issues
This typically indicates: weak fob battery (replace first), damaged fob antenna, or issues with your car's receiver (often in the door handle or rearview mirror). Environmental interference from other electronics can also reduce range.
Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Tip: Newer cars often require dealer programming for first key replacement
Key Fob Issues
Many cars have a resync procedure: 1) Press lock/unlock buttons while near the car 2) Insert key and turn ignition on/off in a specific pattern 3) Use a sequence of button presses. Check your manual for exact steps - procedures vary widely by manufacturer.
Key Fact: Smart keys use radio frequencies between 125 kHz and 2.4 GHz
